Removing default main menu
I wanted to have Bulletstorm-like menu (with real animated characters in the background) so I've made a simple level with that and added Scaleform menu on top. This works great. However, when I create game package using Unreal Frontend the game still displays UT3 menu first (instant action, multiplayer etc). How can I get rid of that?
And also: I'm not using any stock UT3 assets. Can I somehow delete them from my game package so it would be smaller? Currently it has over 500MB and I guess a lot of it is Unreal default data.
